Identifying Cancer’s Food Sensors May Help to Halt Tumour Growth
Oxford University researchers have identified a protein used by tumours to help them detect food supplies. Initial studies show that targeting the protein could restrict cancerous cells’ ability to grow.
Fatty Liver Disease and Scarring Have Strong Genetic Component
Researchers say that hepatic fibrosis, which involves scarring of the liver that can result in dysfunction and, in severe cases, cirrhosis and cancer, may be as much a consequence of genetics as environmental factors.

A Method for Greater Reliability in Western Blot Loading Controls: Stain-Free Total Protein Quantitation
Bookmark and Share

Bio-Rad Laboratories

This application note compares the linearity of a series of dilutions measured by stain-free total protein measurement as well as immunodetection of three housekeeping proteins (ß-actin, ß-tubulin, and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). We found that immunodetection-based measurements of ß-actin, ß-tubulin, and GAPDH protein levels neither showed good linearity nor accurately indicated 10–50 μg of HeLa cell lysate loading levels. By contrast, stain-free total protein measurements exhibited great linearity in the same loading range and its linearity correlated with the immunodetection of a selection of low abundant protein targets: MEK, Akt, and Erk. This study demonstrated that stain-free total protein measurement serves as a more reliable loading control than housekeeping proteins, particularly in the loading range commonly used for cell lysates, 10–50 μg.
